dry or set uniformly, a quantity of water is poured on top of the block Within the mold box. When the block has become properly set or dried it may be removed from the box, and to assist in this opera-tion a piece of suitable textile fabric d is placed in the bottom of the mold, thus serving to prevent the block from sticking in the mold and to give additional strength to the partially dried block.

From the foregoing it will be obif'ious that our method may be readily carried out by an unskilled person, and that the blocks will all have different facial contours owing'to the fact that-the depressionsb made by the trowel are irregular and thatthe suction 0f the face-plate will vary for this reason, depending upon the admission of air through the air holes, 7. It yis very desirable, in forming blocks of this character, to have the faces different in each block in order that they may simulate the natural stone-blocks having roughened surfacesl of different 'contours.

lVe claim:

l. The method of facing concrete blocks which consists in creating suction on.the face of the block while plastic at the same time that cert-ain detached areas on the face of said block are relieved from the suction, thereby producing irregular depressions and ridges on the face of the block.

2. The method of facing concrete blocks which consists in forming irregular depressions in the face of the block While plastic and then creating suction on the face of the block at the same time that certain detached areas on the face of Said block are relieved from the "suction, thereby producingrirregular depressions and ridges on the face 'of the block.

In testimony whereof We Aa-Hix our signaturesin presence of two Witnesses.
